Framing the Conversation
Examining our changed environment
Charting our course forward
Incorporating new library standards
Finding new frameworks for building services
User participation--enlarging the metadata footprint
Open data—a necessity for building innovative services
1/25/09 2Hillmann--ExLibris Seminar
What Do We Know?We are no longer the first place our users go for
information, yet: We still manage many silos of information
important to themBooks, serials subscriptions and licenses, archival
materials, institutional repositories, other project materials
We will need to keep inventory-level information to support acquisitions and circulation
The notion of integrated back room and OPAC seems irreparably broken
What do we do now? 1/25/09Hillmann--ExLibris Seminar 3
What We Must Leave Behind
A view of metadata based on catalog cards
Library software that can’t sort search results better than “random” or “alphabetic”
Search interfaces even Librarians hate (and we know the data!)
Clunky static HTML pages that don’t attract our user’s interest, or guide them well
One silo for books, others for journal articles, images, digitized books, etc. (explain that to a user!)

The RDA You’ve Heard About …
2nd quarter calendar 2009 – RDA content is finalized
3rd quarter calendar 2009 – RDA is released
3rd and 4th quarters calendar 2009, possibly into 1st quarter calendar 2010 – Testing by national libraries
1st and 2nd quarters calendar 2010 – Analysis and evaluation of testing by national libraries
3rd-4th quarters calendar 2010 – RDA implementation ?

Under the RDA HoodA FRBR-based approach to structuring
bibliographic data
More explicitly machine-friendly linkages (preferably with URIs)
More emphasis on relationships and roles
Less reliance on cataloger-created notes and text strings (particularly for identification)
Less reliance on transcription

Example: The XC Project An example of iterative, flexible development
in an unstable world Focus on managing data from a variety of
sources, intended for a variety of purposes “Added value” important at every level
Built an XC Schema to move forward despite the gaps in current standards activities--without carving data decisions in stone
Services operate independently, improvements and upgrades don’t require “central system” changes; new services can be added with little impact on other activities1/25/09Hillmann--ExLibris Seminar 9
What You Might Not Have Heard
JSC has gradually backed away from their original stance that RDA could be expressed easily in MARC21 Full integration of FRBR entities into RDA has
made that problematic
RDA has been developed explicitly to take advantage of the Semantic Web (although there are still residues of past practice)
IFLA is working on formal, persistent registration of FRBR entities and relationships

RDA & FRBR: Registered! RDA Elements:
http://metadataregistry.org/schema/show/id/1.html
RDA Roles: http://metadataregistry.org/schema/show/id/4.html
RDA Vocabulary: Base Material http://metadataregistry.org/vocabulary/show/id/35.html
FRBR Relationships (Sandbox version) http://sandbox.metadataregistry.org/vocabulary/show/
id/90.html
Registered schemas and vocabularies will be available as part of the released RDA tools this summer

Supporting Innovation
Building New Frameworks
Flexible metadata management is essential for building systems in an “uncooked” world Must accommodate multiple “formats” for input
and output Cannot wait for the library world to “settle down”
(it may never do so again!) Will accommodate MARC as one (of many) input
formats and as only one of the output options Must be sustainable as a service, without
commoditizing data output
1/25/09 13Hillmann--ExLibris Seminar
Building New ParadigmsBased on better use of machines; limiting
human intervention to where it makes the most sense
Understanding the changed world of metadata, and where the Semantic Web will be pushing it
Accommodating a variety of “packaging” and transport mechanisms
Collecting and mashing up data from various sources to provide better functionality for users
Supporting innovation from users and others1/25/09 14Hillmann--ExLibris Seminar
Attracting User Participation
The end of descriptive objectivity (social networks = subjectivity)
No more “one size fits all” applications
Learning from Amazon and other successful services Users will participate if they get some value back
Passive participation also important Usage data, circulation (popularity) data,
connections with course management systems, etc. Aggregated data mitigates privacy concerns
1/25/09 15Hillmann--ExLibris Seminar
The Semantic Web LurksPrefers open linked data as a basis for operation
Artificial or proprietary boundaries around data will build disincentives to important innovation OCLC’s proposed record reuse policies very
troublesome
Vendors have challenges in this new world, but maintain an important role in developing new products and services The rewards will go to those who are early out of
the gate, build flexibility into their products, and carefully examine their old assumptions
